This is going to be one of the most drastic changes to the skyline coming up. For what it lacks in height, it makes up for in density, girth and location. This site is laying such an important piece to Toronto's urban fabric IMO.
That skyline render gives a bad perception as CIBC square, One Yonge, the developments along bayside and whatever else is being built in the lower east side of downtown will fill up the empty space. Toronto will have a radically new postcard shot from the lake.
